Trump Unveils 25% Tariff on Countries Trading With Iran

13th Jan. 2026

Trump announces 25% tariff on countries that do business with Iran following the protest crackdown. It came into effect immediately in a move with an aim to increase pressure on Tehran amid a violent protest crackdown. Moreover, the president announced the policy on Truth Social, reinforcing his stance on tougher action against countries that maintain trade ties with Iran.

The image shows former US President Donald Trump in an ultra-realistic editorial portrait, positioned beside the bold word “Tariff” and rising financial charts with the US flag in the background, illustrating his announcement of a 25% tariff on countries and partners doing business with Iran.

However, the White House has yet to release a formal legal documentation or an executive order that clarifies the authority and enforcement mechanism behind the proposed measure. Consequently, analysts said that the announcement raises questions about the legal basis for unilateral tariffs and about how enforcement would operate in practice.

Which countries are affected by the tariff?

In addition, Trump described the 25% tariff as “effective immediately,” and stated that it would apply to all US trade with nations he identifies as doing business with Iran. This decision will impact major economies, including China, India, Turkey, and the United Arab Emirates. It also potentially affects global imports of Iranian oil and other goods. Furthermore, trade experts warn that secondary effects could ripple through global supply chains and raise costs for American consumers.

Pressure Campaign Revived due to Trump’s Tariff

The proposed tariff revives Trump’s earlier “maximum pressure” strategy, which defined his Iran policy while in office. During that period, the US withdrew from the 2015 nuclear deal and imposed extensive sanctions on Tehran. This latest proposal, however, goes further by targeting third countries rather than Iran alone.

According to Trump, the tariff would create a clear choice for US trading partners. Whether they continue commerce with Iran or retain unfettered access to the American market. Supporters argue that such leverage could curb Iran’s behavior more effectively than diplomatic statements. However, critics warn that this risky announcement escalate trade disputes and strain alliances. It will happen particularly with countries that maintain limited but lawful trade with Tehran.

How did other countries reacted on the 25% tariff?

Meanwhile, China and other countries swiftly criticized the unilateral move. They insisted they would defend their economic interests, while also urging restraint and dialogue. Also, Iran indicated that it would keep some communication channels with the US open even as protests and internet blackouts complicated verification on the ground. As a result, diplomats highlight warning of heightened tensions and potential for retaliatory measures.

Finally, although the announcement signals a sharper US foreign policy stance, it also leaves many practical and legal questions remain unresolved for global partners. Meanwhile, legal challenges appear likely, as administrations, allies, and financial markets absorb another abrupt shift in Washington’s trade and diplomatic approach. Moreover, if sustained, the tariffs could reshape regional alliances. Furthermore, it forces companies to weigh compliance and exit strategies and increase consumer prices. Investors also reacted quickly, while pushing commodity and currency markets to reassess risk and exposures.
